Neutron diffraction shows how myelin gets on your nerves

New research has shed light on the way in which our nerves conduct electrical signals around our bodies. The structure of myelin, the layer of insulating fat surrounding nerve cells of vertebrates, has now been analysed in ...

Fastest X-ray images of tiny biological crystals

(PhysOrg.com) -- An international research team headed by DESY scientists from the Center for Free-Electron Laser Science (CFEL) in Hamburg, Germany, has recorded the shortest X-ray exposure of a protein crystal ever achieved. ...

Beating the diffraction limit with nanoantennas

Plasmonic nanoantennas are among the hot topics in science at the moment because of their ability to interact strongly with light, which for example makes them useful for different kinds of sensing. But matching their resonances ...

Electron diffraction locates hydrogen atoms

Diffraction-based analytical methods are widely used in laboratories, but they struggle to study samples that are smaller than a micrometer in size. Researchers from the Laboratoire de cristallographie et sciences des matériaux ...

Earthquake waves: How do they spread?

Propagation of earthquake waves within the Earth is not uniform. Experiments indicate that the velocity of shear waves (s-waves) in Earth’s lower mantle between 660 and 2900 km depth is strongly dependent on the orientation ...

3D potential through laser annihilation

Whether in the pages of H.G. Wells, the serial adventures of Flash Gordon, or that epic science fiction saga that is Star Wars, the appearance of laser beams—or rays or phasers or blasters—ultimately meant the imminent ...

X-ray laser explores new uses for DNA building blocks

(Phys.org) —The founding father of DNA nanotechnology – a field that forges tiny geometric building blocks from DNA strands – recently came to SLAC to get a new view of these creations using powerful X-ray laser pulses.
